9 Claims.

rI his application is a substitute for my abandomed application Serial No. 352,349, filed August .-13, 1940,..and the same relates to cigarette machines of the type that produces a continuous tobacco-lled and sealed paper tube cut automatically as produced into desired lengths. Heretofore, continuous-tube type cigarette machines have been large, heavy, thoroughly non-portable, -ultra-high-speed installations suitable exclusive- 1y for mass production.

An object of my invention is to produce a continuous-tube cigarette machine of such size and weight and such simplicity of construction and operation that it is truly portable, can be carried around by any one, put away when in disuse and brought out for occasional use exactly like any household appliance. Heretoiore, privately owned and Operated cigarette machines have been of the type that load and roll sidewise, one cigarette at a time-a process too slow to be desirable.

An object of the present invention is to make a tobacco-filled paper-tube between the opposed sides of two manually-driven rubber bands and periodically cut-off cigarettes.

Asn object of my invention is to provide means of so forming continuous cigarette stock and automatically cutting off suitable lengths without stopping the continuous movement of the stock.

Another object is to paste or seal the stock by means that automatically removes itself from the stock when continuous movement ceases.

Further objects are to automatically-print, load, form, seal and cut-off continuous-tube cigarettes. l Numerous other obj ects of the invention not at this time enumerated will become readily apparent as the nature of the invention is better understood.

Two continuous cooperating carriers or endless belts, I and 2, formed of resilient material such as rubber or a rubber compound, each being approximately one-eighth inch thick and threequarters inch wide, are disposed for drive by and traVel OVEI pulleys 3 and 5, and 4 and 6 respectively. The pulleys are journaled kinside frames I and 8 which are provided with base flanges 9 and I0 and joined together by post-and-screw mountings at I2, I3 and I4. The pulleys 3, 4, 5 and 6 are mounted on horizontal shafts 3, 4", 5' and 6' respectively, with the band I disposed above the band 2 at such distance that'when the sides of the bands next each other vare :compressed sidewise by spindles or rollers I5 the space between the two bands forms a .cylindrical opening I6, Fig. 4. In this space the cigarette cylinder I8 is held while the glue for holding it together sets and whereby, owing tothe forwardmovement of the belts, the cigarette cylinder, and hence the feed paper, are driven. They belts exert a very considerable outward pressure against the rollers I5, making it practical to Amount them `freely in notches I5 (Fig. 4) in inwardly turned flanges o-f the Vside frames 1 andA 8.

In` the present embodiment, the means of driving the cylinder I8, motor or manual, includes the shaft 5 Yupon which the pulleyA 5 is mounted for rotation about a horizontal axis in unison therewith. On one end of the shaft 5' a spurgear 2l, also joined to the shaft, is driven by' a pinion 2-2 having half as many teeth as provided in the' spur-gear 2|. This. pinion is found on a transverse shaft 25, to which are also secured a Y crank-and-handle 26 and a mitre-gear 2l. The

shaft is squared, on the end opposite the gear 2l as indicated by the numeral 20, thus providing means of attaching a motor-drive which may practically consist of an electric motor with integral reduction gearing of suitable speeds and ratios. When the motor drive is in use, it is preferable to remove the crank-and-handle 26, for which purpose assembly is made by means of a screw Sii. A shaft 35, disposed longitudinally of the machine, is rotatably held in a bracket 3S which is joined in suitable manner to the side of the side frame 8, and held in an end plate 31', which is suitably joined to the ends of` the. side plates 'l and 8. The shaft 35 is driven by a mitregear 40 which engages the gear 2i. To the outboard end of the shaft 35 is pinnedV a castellated collar 4| which engages a castellated, manually adjustable collar d2, to which is joinedatits apex a conical (spiral-helix) spring 43. A flat steel cutter plate 44, Fig. 3, with a cutting edge 45, surrounds the shaft; 35 andi is. held. tight against the end plate 31 by the springA 43 which is secured to it at 48. A flat, substantiallyl U- shaped, spring-xiii). (shown largely in dotted, lines) having` two legs, is joinedy to theinner side ofthe end plate 3 1` as by rivets 5l.. The. tips. of each spring leg are turned at right angles (towardthe observer) as. at 5t andare adapted to. engage holes 55 and 56 in the cutter plate 44, stopping the rotation of the cutter plate by. compression at the hol-e 55; and tensilely, hook-fashion, at the hole 56. A compound cam 51, shown in dotted lines in Fig. 3 and in perspective inr Fig. 3a, having inner and outer: sloping cam surfaces 5S and 59 respectively, is mounted on and rotatively drivenA by the shaft 35 and: is disposed between the flat spring 5t and the inner. face of the end plate 31 engages a. projection en each. of. the legs of: the spring. '59 in such manner that the legs and their engaging portions are withdrawn, one ata time, from the engaging holes55.- and 551 in the cutter p1ate44. The outer cam surface 59 disengages the spring leg` from the edge ofthe hole 55. by sliding engagementv with a projection 55'." on., the spring. 5t; The inner. cam: surfaceY 58 disengages the other spring: leg, from.` the edge of the hole. 55* by asimilar sliding engagementwith a, projectionl 56 on the spring 55d. This. cut-off mechanism workszasfollowsa.

The crank-and-handle 2t, and thereforerthe shaft 25, rotate two full;revolutions`y duringwhich the shaft 2,0. and the pulley 5.1otate once. This issuficient to-advance the cylinder. I the length of' one` cigarette. As the mitre-gear 21 on the shaft makes. two` revolutions, the gear 40, and therefore the shaft. 35, together with the collar 4'2and`thecam 5l, make. one. revolution. Asthe collar rotates it winds the spring 43 which turns thecutter 44. In Fig. 3, the cutter has just cutoffa cigarette and has beenstopped by one leg of the spring 50 at the opening 55 in the cutter plate. When the cam 5l*l now turns a suitable distance, such as 60 to 90, it withdraws the sto-p spring at the opening 55 by means of the slope or hump 59. The spring 48 then turns the cutter plate a few degrees, such as 5 to 10; at which time the other legr of the stop spring 5B catches and stops it at the opening y56. (There are suitable perforations, not shown in the end plate 31 through which the stop-springs project to engage the Cutter plate.) When the caml 51 has turned the remainder of a full revolution, it releases the stop-spring at 56 and the cutter bar springV all the remainder of theway around to the position shown-during which latter motion it cuts-off a cigarette.

A modification of the automatic cut-off just described is a manual cut-off shown in Figs. 5 and 6.

In this modification, the longitudinal shaft 35 is entirely dispensed with. A modified end plate 5d supports a knife holder 6l at 62 in a manner hinged for arcuate movement. A coil spring 65 holds the knife-holder 6| tightly against the endplate 6G and rotatively in its top position (as shown). The knife-holder releasably supports a safety-razor blade 65 used for cutting-off the cigarettes-the blade being manually attachable and removable by the thumb-nut 86. A strikehandle Bl enables the operator to cut-olf a cigarette by a downward striking of the fist. A slot 10.- in the end-plate 5D, and a lanced-out, turnedin portion 'H of the knife-holder 6l limits the arcuate motion, top-and-bottom, of the holder Erl. In order that anaccurate and automatically measured length. of cigarettemay be obtained,.I have devised; means. whereby; when such length hasbeen produced. the machine is topped until thecigarette thus produced is cut-off.. Rigidly joined to the outer end of theshait 20', opposite the crank-andehandle 26, is, rotatably attached a hook or latching-piece 16;, while: on. the, same endof theY shaft 25; is mounted' an arm 'i6 free for arcuate motion. This, arm:A is, turned` toward the latching-piece 'i5 by a spring 7i.. Rotatably mounted onv one end; of the arm IiiV is a latchpiece` 8a which cooperates with4 the latchingpiece 7:5. This pieceSl isY turned (clockwise) by a-.spring 8,! and stoppedfby'a pin 82A firmly j oined to the arm 15. Operationis'as follows:

When the shaft 2l)4 has turned (in thedirection of the arrow) sufficiently far for the conveying of a cigarette of desiredl length, the latchingpiece 15 engagesvthelatch-piece 8,.which,.when turned (counter-clockwise) as far as the stop 82 will permit, stops the rotation' of the shaft 20 and. hence the machine; Operator thenV strikes down handle -'l outting-offthe cigarette. When the turned portion 'H of the knife-holder 6l engagesa turned-over boss 8,5: integral with the arm 75, thus turningthe arm 'i5 through-.a small arc, the latchl mechanism'. ivE--B' is' released. When the latch-pieces separate, the latch-piece springs clockwise sumciently far to throw the latch past latching position whenarm 'i6 is released by the knife-holderv Si.

A paper ribbonof continuous strip'stock, filled With-tobacco byV means presentlyto be described, is drawn, bythe-movement of the rubber be1ts'2 and 3, through a shaper or forming die where justbefore entering the advancing, tubular-passageway between the, belts adhesive application must be made;V At this point,v I` havev provided a moistening device, such as a fountain type mucilage-spreader, generaux/'characterized vbythe numeral I, which ceasesjits'; applying moisture or adhesivel the instantthegfdrivingtorque,on the drive-shaft 2'is relieved.

opposite directions.

the embrace of the bands. The roller is caused to bear upward on the under sideof the vupper portion of the upper band by a spring |08.

As the roller is raised or lowered, the spout |06 respectively makes and breaks contact with the paper. When driving torque is applied to the drive pulley 5, the under portion of the band I extends slightly, causing a looseness in the upper Adesirable since if contact is maintained while the :machine is inoperative, the mucilage will spring A(by capillary action) through paper and tobacco vcausing defect and breakage.

A tobacco loader and strip paper holder, generally characterized by the numeral H9, Figs. '1, 8 and 9, and a shaper. I, are disposed longitudinally and in tandem arrangement with the machine of Figs. l and 2. A wholly manual type of 4tobacco loader IIO has an open top bin ||5for holding the shredded tobacco, and trough H6 of gradually varied cross-section from end to end'in which the paper slides and wherein it receives its load of tobacco. On one end of the bin is firmly aiiixed a free end shaft |1 on which a roll of paper I I8 is freely. rotatably mounted. Paper from the roll is turned through 9 over a form H9. Inoperation, as the handle `is turned with the right hand, tobacco is dragged frcmthe bin to the paper lined trough with the fingers of the left hand. A desired quantity of tobacco may thus be fed to the cylinder as it advances.

The shaper III, (shown in elevation in Figs. '1, 8 and 10, and in cross-section in Fig. i3 taken on the dotted line I3-|3 of Figs. 7 and 10) comprises a support bracketor frame |25, to which is firmly joined a sheet metal cigarette shaping or forming piece |26. This piece is substantially an open-top trough having vertical and parallel sides at the entrance end, and with the sides so developed in form toward the exit end that they lean in until they are freely overlapping for Icausing the paper ribbon to ever more approach a lap-weld tubular form as it passes through it. At the entrance end of the shaper, a manuallyadjustable, spring-actuated tobacco compressor is mounted on top edges of the forming piece |25 by means of a cross-bracket |20. The com- .pressor comprises a spring |30, supporting a disposed a hopper |42 having four sides and a bottom for holding the shreddedtobacco. Be-

Y .tween the trough and the hopper is located a mechanical measuring .device comprising two series of toothed discs |45 mounted on and driven by shafts and |41, which are geared together Vby means of gears |48 and N9 for rotation in These discs project through Afree slots |59 in thebottom of the hopper.r The -shafts |45 and |f|1` are gearedrespectivelyto Tension on the spring |39'is V altered and maintained by the tthumb-nut |32 shafts: |52 and |53, which are the axes of cylin drical brushes |54 and |55 respectively. A further shaft I|0 drives a gear |6I, which meshes with M9, which in turn meshes with |55. |49 also meshes with |48, which meshes with |54. The shaft |60 is driven by a flexible shaft |63 joined to the end opposite the gear IGI. The iiexible shaft is driven by the shaft 35 (Fig-2) to the end of which, at |65 it isY suitably joined. The toothed discs |45 drag a predetermined quantity of shredded tobacco from the bin |l|2 for each revolution and which is thus proportionate tothe linear movement of the paper, and hence they deliver a predetermined quantity of tobacco for each cigarette. The brushes |55, because of a suitable gear ratio, rotate faster than the disc and thus disengage the shreds from the teeth throwing them into the paper-lined trough |4|. With this automatic loader driven by an electric motor, which also drives the cigarette-making mechanism of Figs. l and 2, this becomes a continuous operating machine.

A printing device and reel holder is shown in Figs. 15 and 16. Here a unitary sheet-metal. frame or holder |19 supports a free-end spindle |1| upon which the reel of paper |12 is freely rotatably mounted. The reel is kept on by the thumb-nut |13. To the frame |15 there are also joined a paper guide |15, a fixed free-end spindle |15 for freely rotatably supporting a printing Wheel |80, and a bracket |8| for holding a lighttension flat spring |82 against the paper |83 opposite the printing face of the wheel |80.

The print wheelis held on the shaft |16 by the thumb-nut |95, while the thumb-nut |86 determines the print-pressure. rEhe wheel prints in a manner unlike that common to conventional cigarette machines for it prints lengthwise of the cigarette a substantially continuous line of characters or marks. The print wheel is provided with an ink wheel |99 in a substantially closed case HH.v The outer member of the case is firmly joined to a heavy bent wire |92, which is hinged, at Y|9123 by being inserted under a flat spring |95 held rmly to the frame |10 at |95.

Bent notches |99 and |91 in the free end of the spring |9 provide for holding the wire and hence the inker in tivo positions, |99 operative and |91 inoperative. The case |9 has an outer, lidlike Vcover |99 through which projects inwardly a free-end spindle which holds freely, and rotatably, the inking wheel |95. The cover |99 vis provided with a thumb-nut-like handle 299,

by means of which the cover |99 may be turned Withrespect to the case |9|. A suitable slot cut in the side wall of both case and cover permits contact of ink wheel with print wheel when slots are in a corresponding position. Since the Yslot yin the case is in a suitableiixed position, the

turning of the knob or handle 259 to a proper and marked position opens the slots for inkwheel-toprintwheel Contact. When the machine is putin disuse, the inking mechanism is pressed down into notch |51 and the case closed by the knob 299. The ink in the felt wheel will not nowdry out or deteriorate before the machine is again brought out for use.
